The prevalence of respiratory syncytial virus (RSV) infection among se
verely malnourished children was studied at the University of Benin Te
aching Hospital, Benin City, Nigeria at a time when the infection was
known to be prevalent in the community. Nasopharyngeal washings were o
btained from subjects on admission and thereafter every 4 days until d
ischarge. RSV was detected by ELISA technique. Of 20 well nourished ch
ildren who served as controls, 11 were ELISA-positive for RSV (55%). E
ight (16%) of the 51 patients who were malnourished were ELISA-positiv
e, four of whom (8%) had nosocomial infection. Fever and rhinitis were
the most common presenting features in the RSV-infected malnourished
children. None of the children showed any clinical or radiological sig
ns of lower respiratory tract infection. Malnourished children appear
not to be at increased risk of RSV infection, and those who contract t
he infection usually do not manifest severe disease.
